Answer 1

Question :

• An Elevator descends into a mine shaft at the rate of 6 meters per minute. If descends starts from 10 meters above ground level, how long will it take to reach--- 350meters.

Let's Start :

• Considering an elevator to be at constant speed and the destination to be 350 meters below ground level.

• The elevator has to travel 10 meter till the ground then 350 meters more.

so the total distance travelled is = 360 meters

• If the elevator speed is 6 meters/minute

Then :

➜ Time = distance/speed

➜ 360/6

➜ 60 minutes

➜ 1 hour.

So, the elevator would take 1 hour to reach its destination.
